Today is Corpus Christi, and it is very sad that 2/3 of all Catholics do not believe in the True Presence of Christ in the Eucharist. Christ is real! Christ is truly present in the bread and the wine that becomes the Body and Blood of Christ when the elements are consecrated at Mass on the Altar by the Priest.
We have many resources that we can access to solidfy our belief in the Eucharist. A good reflection for today can be found HERE.
Remember that as a parishioner, you have access to FORMED for free through the kindness of the Knights of Columbus. Registration information can be found in the "Story" section of our website.
In the above reflection, the website https://www.eucharisticrevival.org/ is mentioned. This is perhaps a movement that you would consider joining. At least visit the site.
Finally, his is perhaps one of the most poignant and best resources on the Eucharist. It is available on Formed and is a 3 part series. If you don't have a ton of time, but would like to really focus on the beauty of the True Presence, please watch at least the 3rd episode. Please watch at least the trailer for PRESENCE.
